Because of increasing power densities, microchannel systems are being explored for two-phase cooling of ultra high power electronic devices. Flow instability is a potential problem in any two-phase microchannel cooling system especially for transient applications. With various two-phase flow stabilities possible in a microscale boiling system, the overall cooling performance deteriorates significantly. For better dynamic thermal management of microelectronic systems, a family of oscillatory flow boiling heat transfer correlations and active stabilizing flow control methods have been developed.
